There are a lot of reasons why your AC system freezes up.
Making sure the air filter isn’t dusty and airflow isn’t lowered are the only tasks you can safely fix on your own. If you need to put in a new the filter, you can hasten the defrosting process by turning off the system and turning on the fan. If you have a heat pump, you can turn it to heat mode until the ice has melted.
After the ice is gone, turn the temp back to normal. If your unit freezes repeatedly, get in touch with Boehmers/Cronin Emery Home Services by Enercare to repair the issue.
Here are several other reasons why your equipment may be freezing up.
Insufficient refrigerant—Freezing up can be caused by a refrigerant leak.
What causes a leak?
- Weakened solder joints
- Friction from piping jarring against an object
- Cracked valves
- Slack fittings
How long your equipment has been working and the area of the leak play a part in whether you should repair or replace your AC system.
Dirty evaporator coil—Over time, the evaporator coil becomes dirty and creates issues much like a clogged filter. You’ll progressively get lower airflow until your system freezes or quits cooling. You’ll need to call Boehmers/Cronin Emery Home Services by Enercare to fix the malfunction.
Defective blower motor or relay—A blower motor going at an inaccurate speed or not turning on at all can cause freezing. It can also be sporadic, going at full speed and slowing down after it heats up. Or a relay could make it run one time and not the following time. In either situation, you will need to contact Boehmers/Cronin Emery Home Services by Enercare to correct the trouble.
Requesting regular AC maintenance can help you skip this issue. Our pros will comprehensively examine and clean your system, which typically allows us to pinpoint little issues before they turn into huge problems.
